What to do when Hermle quartz is discontinued?

The Hermle quartz clock movements are discontinued and no longer available. This means if your quartz clock movement says 2214 or 2215 and has a pendulum, or if it says 2114 or 2115 non pendulum, its no longer made.

We have these alternate movements that have the equivalent sound quality and lasts longer than the Hermle units. There are more features and do not seem to break or have issues during daylight savings adjustments like the Hermle units did after years of service. To get the new movement, three things are required. First is to be sure the new one will fit size wise. Then convert the hand shaft from the old one to the new. Lastly get new hands as your old ones will not fit.

How to replace an obsolete Hermle quartz clock movement

The Hermle quartz clock movements had a different hands post, and also a different mounting method however. This has to be taken into consideration during the quartz clock movement conversion to one of these fine units.

Basically the Hermle quartz clock movements had a nut that went through the dial side, and into the front of the movement to mount it to the back of the dial. The new unit instead has a post sticking out of the movement that goes through the back of the dial and a hex nut goes on the front dial side to keep the movement mounted to it.

How to remove the old Hermle quartz clock movement

Remove the second hand. Pull it straight and it will come off.

Take off the minute hand nut, just turn the nut to the left when holding the hand still.

Take off the hour hand, its friction fit only, twist and pull toward you.

There is a nut holding the movement. Its tricky as it has two slots on either side of it. Sometimes its on tight. What we do here is just use two big flat screw drivers, put one on each side of the hand shaft in the nut and turn both together as the same time to the left. Careful not to scratch the dial, this is easy to slip and do.

The movement will fall out of the back.

How to measure the hand shaft length

The Hermle quartz clock movements are measured by the entire hand shaft post that sticks out of the movement, from the plastic and all they way out. We measure this different as we go by just the threaded post that goes through the dial and mounts with the hex nut only.

Hermle used three hand shaft lengths on there base units, these lengths are 16mm, 21mm, and 26mm. There was a time some of the 26mm were modified internally to create a extremely long hand shaft, something like 1 1/4 or 1 1/2 inches, if you have one like this there is no luck for replacement.

The following is a guide line for the old Hermle quartz hand shaft length, to the length of the threaded post to order from us. It makes it simplistic to just do the following 1. measure the hand shaft on your current Hermle quartz clock movement, 2. Convert to the post length needed with the below information, 3. order whatever movement you would like from us with that post length.

16mm (About 5/8") = Get a 5/16 post

21mm (About 3/4") = Get a 7/16 post

26mm (About 1") = Get a 11/16 post

Next step to replace the Hermle quartz

Now that your old unit is out of the way and you have converted the old hand shaft length to the new post length, we are ready to shop for a replacement. The next step is to take note of the overall size of the new movement and be sure that it will fit in behind the dial ok.

The new unit maybe taller or wider and we just want to be sure it will fit in there. If verified its ok, we can pick a new unit with the post length that was converted. Be sure to get new hands when your done, they are on the same page as the product. This is your old ones will not fit without modifications.
